L3Harris Unveils Dual-Arm Robotic System to UK Defence Experts

In November, L3Harris Technologies showcased its latest advancement in robotic technology to the UK Ministry of Defence (MOD) operators during an event at the Defence Science and Technology Laboratory (Dstl). The demonstration, held at MOD Kineton, featured a dual-arm robotic payload specifically designed for explosive ordnance disposal (EOD) and other intricate missions.

Since 2011, L3Harris has been collaborating with Dstl on robotics research, culminating in the integration of a dual-arm system onto existing robotic platforms. This innovative payload was successfully mounted on the T7 robot, incorporating HDT Global’s Adroit dual-arm manipulator, all controlled via L3Harris’ advanced haptic controller.

Key Features of the Dual-Arm Robotic System:

• Enhanced Dexterity and Strength: The dual-arm system offers operators a blend of high-strength lifting capabilities and precise movements, enabling tasks such as unzipping bags or dismantling pipe bomb casings. This combination of flexibility and range of motion allows for faster and more efficient threat neutralization compared to traditional single-arm systems.

• Advanced Haptic Feedback: L3Harris’ haptic control system provides operators with tactile feedback, enhancing precision and reducing workload by 20%. Research with the U.S. Army Research Lab confirms that this system also shortens task completion times by the same margin.

• Versatile Application: Beyond EOD tasks, experts from various defense fields are exploring the dual-arm system's potential applications in chemical, biological, radiological, nuclear (CBRN), and explosives detection missions.

Specifications of the T7 Robotic System:

• Weight: 710 lbs (322 kg) with arm and batteries installed.

• Dimensions: 47.3 x 27.6 x 45.7 inches (120.1 x 70.1 x 116.1 cm).

• Power: Operates for over 8 hours, depending on the task, powered by 12 BB-2590 batteries.

• Speed: Exceeds 5 mph (8 kph).

• Mobility: Equipped with a skid steer track system, it can climb stairs and slopes over 45° and traverse lateral slopes over 30°.

• Manipulator Reach: Offers a horizontal reach of 87 inches (2.2 m) and a vertical reach of 122 inches (3.1 m).

• Lift Capacity: Can lift over 250 lbs (113 kg) near the chassis and 60 lbs (27 kg) at full extension.

• Gripper: Features a force-sensing gripper with a non-conductive wire cutter.

• Disruptor Support: Capable of supporting up to four disruptors, including two large disruptors such as PAN, PIGSTICK, HOTROD, and RE70.

The demonstration also highlighted another T7 robot equipped with deployable sensor applications for realistic mission scenarios. L3Harris’ T7 and T4 robotic platforms are already in service with military forces in the UK, U.S., and Australia, underscoring their proven reliability and effectiveness in real-world operations.

Dr. Paul Bosscher, Advanced Concept Engineer at L3Harris, emphasized the significance of gathering feedback from MOD personnel who may deploy the system in real-world scenarios. He noted that discussions at the event indicated broader applications beyond EOD, opening new possibilities for defense and security operations.

This demonstration marks a significant milestone in robotic technology, showcasing L3Harris' commitment to enhancing operational capabilities and ensuring the safety of defense personnel through innovative solutions.
